Indeed, there have even been cases in which purportedly “natural” weight-loss and other supplements, like those containing the much-vaunted Acai Berry, have been contaminated (either intentionally or through sloppy production methods) with stimulants like oxilofrine, ephedrine and clenbuterol and steroids like nandrolone.

Represented by Denver attorney Antonio Gallegos, Olivera appealed the decision to CAS, arguing that the arbitrator had not considered the possibility that she had used an earlier version of the supplement, which did not include mythelsynephrine – the chemical equivalent of oxilofrine – on the product label.

Earlier this month, the International Court of Arbitration for Sport reduced her suspension to 18 months after finding that she had unintentionally ingested mythelsynephrine – the chemical equivalent of oxilofrine – while using a supplement marketed as Hyperdrive 3.0+.

Oliveira, who lives and races in the United States, was originally suspended for two years after testing positive for oxilofrine, an amphetamine class stimulant, at the Giro del Trentino Donne in July of 2009.

“The panel concludes that Oliveira’s testimony and the other corroborating evidence establishes to its comfortable satisfaction that she did not intend to enhance her sport performance by unknowingly ingesting oxilofrine,” the decision noted.
